I think my daughter could be pregnant. She wont talk to me and asking her about it is out of the question.

She's taking a lot of aspirin because her head hurts and sometimes I see her face and she looks like she's having nausea.
My daughter has been avoiding me since I started noticing all this.

She wont go out on the quad bike or dirt bike anymore. She's being sick in the morning. I'm almost sure she's pregnant, but I would like her to confess whether or not she's pregnant to me. How do i get my daughter to talk to me without pushing her away?
